gah, I give up for now. playing walls is just boring (except for the match against the aggro artifact deck where two copies of
Nicol Bolas, Planeswalker actually helped win the game against an islandwalking
Inkwell Leviathan and his no less than three pretty much unblockable
Juggernaut buddies in play at one point, that was fun). being too stupid to mulligan in round 7 certainly doesn't help
anyhoo, since we have no decklists for that challenge yet I might as well give you one.

Nicol Bolas, Planeswalker (you somehow have to deal with cards like Jenara, Assura of War after all or, of course, you can just pray for decent matchups)

Felidar Sovereign (who, for all intents and purposes are pretty much walls if you cant stop the opponent from amassing first-striking Kobolds and Soldiers)
first attempt was plain G/W with
Ajani Goldmane who makes your walls formidable and produces humongous Avatars which will get chumpblocked till kingdom come.
Rolling Stones is not really an option as a 4-off imho since you have no way to deal with a stalemate. the mentioned Rings certainly have merit.
